TRUNK-LOCK.

SPECIFICATION forming part of Letters Patent No. 300,850, dated June24,1884.

7 Application filed February 23, 1884. (ModeL) To all whom it mayconcern.-

Be it known that we, GEORGE CROUCH, of the city and State of New York,and HER- MANN AI-IREND, of Newark, in the county of Essex and State ofNew Jersey, have invented an Improvement in Trunk-Locks, of which thefollowing is a specification.

Trunk-locks have been made withina circular case upon a hinged hasp, thelock having a turn-bolt at the back end, which bolt passes through anelliptical opening in a septum at the bottom of a cup that is secured tothe trunk. In these trunk-locks it is necessary to make use of a key tolock the trunk. This is very unhandy, because trunks often have to beclosed and locked by one person while another, who may be absent, hasthe key for opening such lock.

Our invention relates to the combination, with the hinged hasp and cupsecured to the trunk, of a spring-lock that catches by simply pressingthe look into its place, but which requires the proper key for openingthe same. \Ve also construct the parts of the spring-lock in a peculiarmanner, so as to be strong and compact.

In the drawings, Figure 1 is an elevation of the hasp. Fig. 2 is a sideview with the hasp partially swung back. Fig. 3 is a horizontal sectionat the line 00 00, and Figs. 4; to loshow the detached parts of thelook.

A represents a portion of the bottom part of the trunk, and B a portionof the top part or lid. Usually there is a skirt or band, 0, around thelid where it adjoins the bottom of the trunk. The cup D is provided witha flange, d, that rests against the outer surface of the trunk, andaround the cylindrical cup there is a screw-thread, and the flanged nutE serves to secure the lock-cup firmly to the trunk. This part issimilar to that which has before been used, as seen in Patent N 0.235,130, except that the opening in' the septum e for the locking-bolt,instead of being elliptical, is round. The hasp G is hinged at g to thestock H, which is bolted firmly to the trunk, and F is the lock-case,which is circular, as in aforesaid patent. The cap-plate f of the lockis preferably circular, as shown. It is let into 50 the face of the haspand closes the lock-case.

It is preferable to secure this cap-plate by .shown in the drawings.

countersunk rivets instead of the screws The lock itself is composed ofthe bolts I I, that are pressed apart by the spring 70. Each bolt ismade with a rounded head, which is nearly a quarterspheroid, as at Z,and next to the end is a neck, which is nearly a half-cylinder at n.Next to this is a square portion, 0, that slides in a square opening atthe back of the lock-cup, and within the lock-cup there are the flangesIt is to be understood that when the heads Z are closed together theycan pass through the round opening in the septum e, and that when theyspring apart the heads Z pass behind the septum, the necks a beingwithin the hole in the septum. The shape of the heads Z is such that thebolts will be pressed together and the heads pass through the hole inthe septum by simply pressing the hasp and lock-case back to theirplaces; hence the trunk can be locked without the use of a key, which isa great advantage in trunk-locks, and one which has not been heretoforeattained in hasp-locks and lock-cups. The flanges p at the back of thebolts, being within the circular lock-case, prevent the bolt drawingout, and the square opening in the back of such case forms a guide tothe parts as they move. lVe remark, however, that these flanges might beextended within the 80. case, and pivoted so as'to swing in oppositedirections instead of sliding. Within the lockcase, and next to theflange of the bolt, there is a disk, 1', having cams that act upon thebolts to draw them toward each other when the disk r is 8 5 partiallyrevolved. These cams are shown at 3 and by dotted lines in Fig. 4 as atthe back of the disk, and are at the edges of an elliptical recess, intowhich the flanges of the bolts enter. \Ve however remark that eccentricslots in the disk-receiving studs on the bolts may be employed, ifdesired. The stud 6 for the key 25 is in the center of the disk 9-, andthere is an opening at 7 in the disk, into which the proj ecting bit 17of the key enters to turn the disk 5 in moving the bolts. There is astud at 8, fixed firmly in the bottom of the lock-case, and projectingup through the slot 30 in disk r, and receiving suitable tumblers, andupon the disk 1' is the stud 40, or fence of such tumblers. Ioo WVeprefer to use the notched crescent tumblers u c, which are held in placeby the stud 8 and the disks a v, the edges of which fit within thelock-case. The springs 18 and 19 are within the circular case andbetween the back ends of the respective tumblers and the notch at theinside of the case, and the ring 21 serves to fill out the space withinthe lock-case and hold the parts properly in place.

It is to be understood that the notches in the tumblers are to beadapted to holding the stud, except when the bits of the key move thetumblers, so that the stud can be moved out of the notches as the disk ris partially revolved to draw the bolts toward each other and unlock thelock. The surface of the flange d and the rear surface of the hasparound the cylindrical lock-case are recessed for the reception of thering 20, which ring is connected to the flange d by a loop at its upperportion, so that when the hasp is unlocked the ring can be swung out andused for lifting the lid or cover of the trunk or box.

\Ve claim as our invention 1. The combination, with a hinged hasp andthe lock-cup, of a lock-case upon the haspand self-acting hookedspring-bolts to connect with the lock-cup when the hasp is pressed toplace, substantially as set forth.

2. The combination, with a hinged hasp, of a lock-cup having a flangeand a septum with a circular opening, a lock-case upon the hasp,self-acting spring-bolts with heads to pass into and hold the lock inthe lock-cup, substantially as set forth. I

3. In combination with the hinged hasp, a lock-case having an opening atthe back, spring-bolts with heads passing through that opening, a camwithin the case to retract the L spring-bolts, and tumblers Within thelock-case to hold the cams, substantially as set forth.

4; The circular lock-case, in combination with the two -partspring-bolts projecting through an opening at the back, and a diskwithin the lock-case, having upon it the keystud, and cams to actuatethe bolts, and a stud on the disk and tumblers, substantially as setforth.

5. The combination, with the circular loekcase and hinged hasp carryingthe same, of spring-bolts projecting at the back of the case, camswithin the case actuated by the key for drawing the spring-boltstogether, and tumblers to control the movement of the cams,substantially as set forth.

6. The combination, with the hinged hasp, circular lock, and lock-cup,of a ring intro duced between the hasp and the flange of the cup, theparts being recessed for the reception of the ring, substantially as setforth.

7 The combination, with the circular lockcase, of spring-bolts, cams foracting on the same, segmental tumblers, a' pivot for the same, andbow-springs confined between the tumblers and the notched inner surfaceof the case, substantially as set forth.

Signed by us this 18th day of February, A. D. 1884.
